7 Claims. (01. 137-13) This invention relates to improvements in firehydrants, and has for an objectthe provision of an eificient and durablehydrant of relative simplicity of form and low manufacturing cost.

Another and more specific object of the invention is to provide ahydrant so designed that the gate or valve when open constitutes adeflector to direct the water stream to the nozzle to thereby reduceeddy currents within the hydrant structure and to insure an efficientflow of water therethrough to the nozzle.

Still another object of the invention is to provide a hydrant whereinproper seating of the gate or valve when closed is assured.

A further object of the invention is to provide a hydrant having upperand lower separable sections through which the gate-operating mechanismextends, together with means for so coupling the porti'onsof saidmechanism occupying said sections that they readily separate uponremoval of the upper'section, thereby preventing damage to ordisplacement of the gate mechanism occupying the lower section byaccidental displacement of the upper section. A

, A still further object of the invention is to provide a hydrantwhereinthe casing is provided at the bottom" With;a drain port, togetherwith novel and positive means for closing said drain when the hydrantgate or valve is unseated.

Another object of the invention is to provide a hydrant wherein theoperation of unseating the gate or valve is a relatively rapid'one.

The invention further resides in certain novel structural featureshereinafter set forth and illustrated in the attached drawings, inwhich:

Figure 1 is a vertical sectional View of a hydrant made in accordancewith my invention;

'Fig. 2 isa plan View of the upper portion of the hydrant, and

Fig. 3 is a plan view of the lower portion of the hydrant with the upperportion removed. -With reference to the drawings, 'a hydrant made inaccordance with my invention comprises upper and lower casing sections Iand 2 respectively which are adapted to be connected through the mediumof bolts 3 which pass through flanges 4 and 5 atthe lower and upper endsrespectively A shaft 8 is seated for rotation in a central 'depressedportion 9 of the head plate 6 and projects downwardly through an openingin the botto rnfof said recess, the projecting portion of the shaftbeing adapted to r'eceive a second shaft I I which is held in placewithin the socketed lower end of the shaft 8 by means of a pin I2. Asi1- lustrated in Fig. 1, the shaft 8 is provided with a projectingflange I3' which bears upon the bottom of the head plate recess, and thesaid shaft 5 is held rotatably in position within the recess through themedium of a stufiing box I4 surrounding the shaft and threaded into therecess in the head plate above the flange I 3 of the shaft.

Packing is confined within the stuffingbox I4 10 described above, thisdome being apertured for 0' passage therethrough of the upper end of theshaft 8.

The head section I of the hydrant is provided in the present instancewith a discharge nozzle I9 which in the present instance is threadedinto 25' a boss 2| in the side of said head section and is adapted forreception of a' cap 22 which nor-- mally closes this discharge port. Itwill be noted that the aforesaid described arrangement of parts is suchthat the shaft II extends downwardly through the center of the headsection I whereby additional nozzle outlets for the head section may beemployed projecting at various points around the head section withoutbeing obstructed by said shaft.

The lower or base section 2 of the hydrantjs provided at one side withan inlet port 23 which is normally closed by a gate or valve 24, asuitable seat in the'form of a ring 25 being secured within the inletport extension 26. The gate 24 comprises abody plate 21 and a face plate28 suitably secured 'thereto and adapted for engagement with the seat 25when the gate is closed; At the inner'side of thebody plate 21 arelugs'29, see

'Fig. 3, which are apertured for reception of a pin 4 3| through themedium of which the gate is'pivotally secured to the ends of a pair ofarms 32. As shownin Fig. 3, the ends of the arms'32 which are connectedas described to the gate are confined between the lugs 29 and small lugs33 spaced outwardly of the said lugs 29 "as shown.

The opposite ends of the arms 32 are provided with recessed bosses 34which receive trunnion pins 35 projecting from opposite sides of a nut36, this nut being carried by a threaded stem 31 55.

extending longitudinally of the lower section 2. The lower end of thisstem is supported in a vertical bearing 38 in the bottom of the hydrantsection and is adapted at its upper end to be connected with the lowerend of the shaft l I through the medium of a coupling 39. This couplingis secured through the medium of a pin 4| to the lower end of the shaftII and fits slidably over the rectangular reduced upper end 42 of thestem 10 31. The nut 36 is provided with an extension 43 which extendsupwardly in the base section 2 of the hydrant substantially parallel tothe stem 31, and this extension has at its end a transversely lprojecting portion 44 which slidably embraces the stem 31. The extension43 has a longitudinal web 45 which also slidably engages the side wallof the hydrant section 2 and is confined 'between parallel guides 46which project inwardly 20 from the casing wall. The entire nut structureis thus permitted free movement longitudinally in the base section 2 ofthe hydrant casing, but is prevented from rotation about the stem 31.

As shown in Fig. 3, the bosses 34 of thearms 25 32- are rounded at theirouter sides and fit within vertical guide recesses 41 formed in theinner wall ofthe hydrant casing 2. This arrangement permits pivoting ofthe arms about the trunnions 35, but insures retention of the arms uponthe trunnion pins. At the same time provision is made for readilyseparating the arms 32 from the trunnions when the nut is elevated to aposition clearing the arms from the guide recesses 41. It will be notedfurther in the event that the stem 3.1 is unscrewed from the nut 36, thenut and the arms 32 are still supported in their relative positions byreason of the nut 36 being retained between the guide elements 46, andthe bosses 34 of the arms 32 being similarly retained within 4,0; theguides 41. At the same-time, the. entire valve assembly, after the stem31 has been removed, may also be removed from the casing base section byturning the gate inwardly toward the nut from the open position shown inbroken lines in Fig. l.

45 In manipulating the gate to the seated and to the open positionsthrough the medium of the stem 31', the gate is guided in a normal pathby a pair of cylindrical lugs 48 which project transversely fromopposite sides of the gate. These 50: lugs cooperate with the undersidesof a pair of curved ribs 49 which project inwardly from the oppositeside walls of the casing. In opening and closing, the lower edge ofthe-gate slides upon a rib 5|, and thegate is confined to a normal pathon this rib by engagement of the projections 48 with the ribs 49. Thegate being flexibly secured to thearms 32 adjusts itself to the seat 25so that acomplete seal is insured. In the fully open position, however,the cylindrical projections 48 clear the inner endsof the ribs 49 asshown in brokenlines in Fig. 1, and thereby permit adjust mentof thegate inwardly to a substantially vertical position permitting withdrawalof the gate from the casing when the stem 31 has been removed asdescribed above.

A drain'port 52 is provided in the bottom of the casing 2, this portbeing surrounded by a sleeve 53 threaded into the port 52- and having inthe side thereof ports 54. The upper end of .the sleeve 53 is slightlyflared to permit ready entrance of a plunger 55 on the lower end of astem 56,which projects upwardly through the nut 36v and through a sleeve51 threaded into and projecting downwardly from the bottom of'the' nut.At its 75: upper end, which projects beyond-the upper end of the nut, isan enlarged head portion 58 which when the nut is elevated to close thegate insures elevation of the plunger 55 to the position shown in Fig. 1wherein the drain opening 52 and the ports 54 are open to admit passageof water from the interior of the casing 2. The plunger 55 consists of arubber or other suitable sleeve 59 which embraces a terminal portion 6|of the stem 56 of reduced diameter and which is confined between Washers62 and 63 on the stem. When the nut 36 is moved downwardly on thethreaded stem 31 to open the gate, the sleeve 51 engages the upperwasher 63 and forces the plunger 55 downwardly in the sleeve until thewasher 62 engages the shoulder 64 at the lower end of the sleeve.Further downward movement of the nut has the effect of compressing thesleeve 53, thereby insuring a positive sealing of the ports 54 andpreventing flow of water from the drain. Movement of the nut 36 againclosing the gate 24 by engagement of the nut with the head 58 insureselevation of the plunger to the position shown in Fig. I wherein thedrain is open.

It will be apparent from the above description that the device isextremely simple in form, easy to assemble and readily dismantled. Thedrain is also simple and positive in operation, and the arrangement issuch that in the event that the head casing l is partially or completelybroken off, the shaft H immediately frees itself from the stem 31, sothat the gate mechanism itself is unaffected and undamaged. The portion44 of the nut 36 also acts to reinforce the stem 31 to prevent damagedue to displacement of the stem from the normal position. There may ofcourse be modification without departure from the invention.
